' ,WATER-nomen# 1 lLike parts are indicatedby similar 4characters of reference throughoutthe several views. l Referring to thedrawingfs,v 1 is the cylinder provided with heads 2--3 connected'by suitable tie bolts i in the usual manner.'

In Fig. 1. the motor is shown as secured to a base Vwhich in turn is mounted on the lid of the washer indicated at`6.

Nithin the cylinder 1 is a reciprocating `piston 7 divided by a partition wall 8 into4 two non-conneeting chambers; an inlet chainber Qand an exhaust chamber 10. Portsor valve openings 11 enter the inlet chamber 9 from opposite sides of the piston. Mounted Awithin the chamber 9 is a valve 12 adapted to alternatelv close the openings 11, and provided with oppositely disposed stems 13 extending outward through the openings l1 beyondthe faces of the piston. The valve 12 is adaptedto seat against the inner side of the ports 1 1, closing one port and opening the other alternately as the piston reaches the ends of its stroke, in opposite directions.

Ports 14u14 enter the exhaust chamber from. opposite sides of the piston, Said ports are controlled by valves 15-15 ar ranged on a common stem 16 and adapted to seat against the outer sides ,of said piston.

' The valves 15-15 are so spaced on the stein that when one port is closed the oppposite port is open, the valves alternating open and closed positions at the ends 4of the piston the'head 2 and may be provided with a rack 22 to engage "with a driven inion or may connect to a crank as desire( 'The piston rod 2() is preferably solid and by screwing, :therein closes one end of the central bore of the piston. An inlet pipe 23, engages the oppositeend of the central bore of the piston and extends outward through a stu fling box An outlet pipe 25 extends centrally-through the inlet pipe 23'and lis 'screw threaded into'a reduced portionof thel fcentral hereof the piston as shown in. .Figuil Yokes'26 on,V either side ofr the piston `con-` difleation showing theusfeif astuffing l n l nectjiwith'the.respective stems of the inlet l,

tion as the piston approaches the limit of its4 stroke, the yoke contacts with the corresponding spring. The spring bearing against the. cylinder head resists the further movement of the piston, bearing on the central part yoke intermediate the valve stems.

'lhe yoke acting over the spring as a lever on a fulcrum will tend to equalize the force on the respective valve stems, or distribute the resistance, whereby one set of valves will not be caused to seat in advance of the other r as may be the case When the respective valve stems are operated independently by independent contact with springs or the cylinder' head.

Upon the contact of the yoke 26 with the corresponding spring the water pressure will cause the yoke to bear upon the spring until the pressure of the yoke upon the spring is I suflicient to overcome the inertia or resistance of the valves, and the valves will be 1 shifted to close' the open ports, and open those previously closed, whereby the water pressure will be admitted to the opposite side of the piston and the movement thereof reversed. The spring not only forms a fulcrum on which the yoke 26 will teeter as before described, to equalize the movement of the valves but will also form a yielding buffer, which will relieve the jar incident to the contact of the piston.

One of the objects of the construction just described and advantages resulting therefrom is that the valves are operated to instantly and completely cut off the water supply at the limit of the piston stroke.

Extending from the cylinder head 3, referably having its inner end forming the g and of the stuffing box 24, is an extended hollow casing 29, having thereon a screw threaded connection 3() for the water supply conduit 31, and a similar connection 32 for the exhaust conduit 33.

The water supply pipe 23 before described extends from the piston through the stuffing box 24 into the casing 29, telescoping there-A with and preferably having a sliding it within said casing; The water outlet pipe 25 there is thus produced a motor possess- -ing the particular features of advantage be- V`fore enumerated as desirable, but which` extends through said inlet pipe and telescopes with a pipe 34 secured within the case 29. The pipe 34 is stationary while the pipes 23 and 25 reciprocate within the case 29. The outlet pipe preferably extends beyond the end of the pipe 23 and surrounds the pipe 33. However, the results would not be different if the pipe 25 was shorter than the pipe 23 orarranged to telescope within the pipe 34.

On account of the great overlapping length of the pipes 25 and 34v it has been found in ractice that a stufling box to prevent the eakage Aof water in either direction intermediate the walls of said pipes is unnecessary. However, if through irregularity of the tubing forming said pipes or by improperA iittingof the respective pipes leakage should occur, a stuffing box 35 maybe provided as in Fig. 4 which is screw-threaded ou the extremity of the pipe 25 and provided with. packing 36.

The operation of the device is as follows: The'water entering under pressure through the supply conduit 31 into the casing 29 passes through the inlet pipe 23 and port 1S into the inlet chamber 9. In the'Figs. 1 and 2 of the drawings, the piston is shownas just beginning its stroke to the left the respective. va ves having been operated to open the right inlet port and the left exhaust port by the contact of the yoke with the spring 28 as described'. y

The water fromv the chamber 9 is flowing as indicated in Fig. 2 throughlthe inlet polt 11 into the Vcylinder space at the right vof the piston driving said piston to the left. At the same time the spent water to the left of the piston is entering through the vleft port 14 into -the exhaust chamber 10 passing. thence through the port 19 and the outlet pipes 25 and 34 to the exhaust conduit 33. At the limit of the piston Istroke to. the left the yoke 26 in advance of the piston will engage at its central part the spring 27. The continued movement of the pistonwill, by the pressure upon or resistance of the spring, move the respective' valves to analternate relation of open and. closed ports when the 'piston will travel to the right, under the in. f uence of the waterunder pressure delivered to the left side of the piston bythe said reversal of the valves.

with the tub, washer, churn, ice cream freezer, or other receptacle, with the casing 29 projectinff well beyond the periphery y"of the receptacle and the supply and: exhaust conduits stationarily located beyond possible interference with the operating parts of the motor or with the cover ofthe v,receptacle when open. While the device has been describeiias a Water motor, Iit is notlimited to such use but other actuating media may a{F1-onf the above description it is apparent obviously is susceptible of modification its form, proportion, detail construction,-a1nlv arrangement of parts, also in its application CIJ end use of actuating medie Without de erting from the principle involved or sacri icing any of its advantages.
